The BAC Estimator

Have ever wondered what your blood alcohol concentration (BAC) might be after having those couple of drinks?  This is different than your breath alcohol (BrAC) but everyone in the DUI arena incorrectly says BAC to refer to both BAC and BrAC.  So will will play along and use the popular term BAC.

Generally a man absorbs .02 and a woman .03 per every standard drink.  These are averages, which may or may not apply to you and are influenced by stomach contents like food, other liquids, and rate of drinking as well.  Elimination rates vary as well but generally an average used in the scientific community is .015 per hour.
